Spirulina and chlorella are two different organisms often sold as one thing. Spirulina is a cyanobacterium, chlorella is a green algae with a tough cellulose cell wall that has to be broken to be digestible — which is why cracked cell wall chlorella is the only kind worth taking. Ours is organic spirulina and cracked cell wall chlorella, with the full amount of each stated on the label rather than hidden inside a blend. Two algae, nothing else — no filler, no binder, no bulking agents. Made in the UK to GMP standards in vegan capsules, and batch tested for heavy metals. How to take: take with food, following the dose on the label. Before you take it: speak to your GP first if you take any regular medication, particularly blood thinners, or if you have a thyroid condition or an autoimmune condition. Not suitable for anyone with phenylketonuria (PKU), or if you are pregnant, breastfeeding, or under 18. Food supplements are not a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the stated dose.
